  • No audio recorded on videos

    No audio recorded on videos

    macOS Version: ProductName: Mac OS X ProductVersion: 10.14 BuildVersion: 18A391 Kap Version: Version 2.2.0 (2.2.0.880), but tested on Version 3.0.0-beta.1 (3.0.0-beta.1.1006) too

    Steps to reproduce

    1. Open Kap
    2. Click microphone icon so audio is toggled on: image
    3. Open Preferences and confirm that 'Record audio' set to the correct device (in my case, just the standard Built-in Microphone): image
    4. Open Sound system preferences window and confirm device is selected and levels are visible on Input tab: image
    5. Perform a recording in Kap, keeping the Sound system preference panel open to observe levels
    6. Try and play back resulting recording. Not there is no audio in the Editor or when saving the file as an MP4.

    Current behaviour

    No audio recorded with Kap videos. Settings all appear to be correct -- audio toggled on in Kap, device set correctly, levels are clearly visible in the Sound preference panel, but still no audio.

    Expected behaviour

    Audio should be recorded with a video.

    Workaround

    Use Quicktime Player with equivalent settings; recording works with sound; I tested this immediately after trying and failing with Kap.

  • White bar into the top

    White bar into the top

    Hello folks!!

    Thanks for your work, I was really looking for a similar idea and I think that you are doing a really good job. I don't understand why we have this white bar in the top of the screen when we start a record.

    Can you help explain me why? :) Thanks a lot. It is also into the final video

  • TypeScript rewrite: Exports window

    TypeScript rewrite: Exports window

    Rewrites main/renderer code for exports window. Also revisited some logic in the Conversion/Export classes created in the Editor rewrite. Fixed some small issues and added a few things:

    • Retry button on Editor window for failed/canceled exports
    • Retry option in the export menu in the Exports window
    • Copy option in the export menu in the Exports window
    • Better error/cancelation handling in export process

  • Add fullscreen and app crop selection options

    Add fullscreen and app crop selection options

    This PR adds the following features: https://github.com/wulkano/kap/issues/300, https://github.com/wulkano/kap/issues/298, https://github.com/wulkano/kap/issues/212

    In order to get this to work, I made the following package: https://github.com/karaggeorge/mac-windows that returns the windows in the current screen along with their information and given an application name it brings it to the front

    I wasn't sure what the design should look like. For now, I just added another select next to the aspect ratio one.

    When an Application is selected, if a user either resizes the crop window or changes the width/height inputs the select will unselect the application. Selecting an Application will also set the appropriate width/height/aspect-ratio in the other inputs.

    The package I made only allows the main window of an Application to come to the front. For example, if you have 3 different Finder windows open, only the last used one (main) will show up. The AppKit Swift library only supports that for now.

  • Better error handling

    Better error handling

    Creates a new dialog window (much more flexible and truly async compared to system dialog)

    It might seem a bit more complex than it needs to be for this PR, but I needed the extra functionality for another PR coming soon.

    Uses that to create better error handling. Logic goes as follows:

    For each error,

    • If it's related to a plugin, show a dialog, allow copying and if we know the repo of the plugin, offer a button that opens an issue with the details of the error on that plugin's repo.
    • If it's not related:
      • If we're offline or analytics are not allowed, show dialog with ability to copy
      • Otherwise:
        • Send to sentry, grab the eventId
        • Use the eventId through a serveless function to find the related Sentry issue (takes about 8 seconds).
        • Check if we have a GH issue with that Sentry issue linked to it
        • If we do, offer a button to open that issue
        • If we don't, offer a button to create it with a pre-filled body along with the Sentry-related ids that will allow the issue to be tracked in the future

    For right now this is the serverless function: https://github.com/wulkano/kap-sentry-tracker

    It's linked to a test repo I made for now. Also, it checks for 3 different types of Sentry issue id, and it also looks only at issues with the sentry label. I did that to limit the queries to the GH api, but I think when users create an issue they can't automatically assign a label, so I might need to remove that, or we might need a webhook that checks if a new PR is opened and it has those sentry ids, it labels it automatically.

    Also, added system colors and accent color as css vars that we can use in the UI from now on

  • Don't ask again if I want to discard a recording

    Don't ask again if I want to discard a recording

    macOS version: Not relevant Kap version: I am not sure. The About Kap option seems to make it crash! Within the last year though.

    Steps to reproduce

    1. Make a recording.
    2. Export it.
    3. Close the recording window.

    Current behaviour

    It always asks if you are sure you'd like to discard it. I always want to discard it. Very annoying.

    Expected behaviour

    I think the best solution would be the ability to configure the behaviour between these options:

    • Always ask
    • Never ask
    • Ask for recordings that have not been exported

    Great software btw!
